Capt. Beau Biden left for Iraq Wednesday with his Delaware National Guard Unit.

(CNN) – Vice President-elect Joe Biden’s eldest son Beau left his training base in Texas on Wednesday, bound for a year-long tour of duty in Iraq with his Delaware National Guard unit.

The 114 members of the 261st Signal Brigade were training at Fort Bliss, Texas for the past two months ahead of their mobilization to Iraq. Captain Beau Biden, also Delaware’s attorney general, will serve as an assistant Judge Advocate General (JAG) officer in Iraq, enforcing the Uniform Code of Military Justice and helping troops with legal issues back home.

On their way to Iraq, the unit will make two stops before arriving at a staging area outside of Iraq where they will receive additional training and equipment. The location of the staging area is classified, though most U.S. troops stage in Kuwait before going into Iraq.

The Vice President-elect was able to see his son one last time before his mobilization last weekend in Nevada when the unit had ‘R&R’ leave.

Beau was also given special permission to fly to Chicago to join his family on Election Day but declined, instead watching the returns and President-elect Barack Obama’s speech on a laptop at Fort Bliss.

“This is a different brand of kid,” his father remarked to reporters on the flight to Chicago.

Joe Biden often gets emotional when talking about his family and fought back tears during brief remarks at Beau’s deployment ceremony in Dover, Delaware on October 3.

“I’ve come here many times before – as a Delawarean, as a United States senator. But today I come as you prepare to deploy as a father,” Biden told the soldiers and their families gathered in front of the Capitol building. “Like all of the family members that are here today gathered on this green, my heart is full of love and pride.”

“Never before has a Delaware guard unit been deployed that is better qualified,” he added. “You are the best demonstration of both our nation’s greatness and, equally as importantly, our people’s goodness.”

Beau will return to Delaware next September and though he has tried to tamp down speculation, rumors are swirling about the possibility of his running for his father’s Senate seat in 2010.
